Knowledge Graph Limitation Frustration (KGLF)

[WolfgangFahl]

Today i couldn't get access the my main triplestore of our project (again) due to:

#204

Which is just a bug in the underlying SQL database that never hit me in the last 6 years but did so today.

Its one of many Knowledge Graph Limitation Frustration sources i have found in the last few years.

Therefore i added a new label KGLF

And added it to the example section of my Paper draft
Towards Overcoming Knowledge Graph LimitationFrustration

[WolfgangFahl]

see #209

Top 20 issues in OpenResearch for which triples do not show up in the SQL TripleStore:

select 
  count(*) as errCount,
  object
from 
  smw_triples 
where 
  predicate ='_ERRT'
group by object
having errCount>10
order by errCount desc
